Current season TV shows aren’t available for streaming.
But you can watch back seasons of shows and entire seasons of shows no longer in production on a streaming service.
Netflix and Amazon Prime also have movies and TV series programs from other countries.
I like to watch some from Australia, New Zealand, and UK that are not shown elsewhere on my cable.
I subscribed to the cable tier for BBC America and have been very disappointed. I hoped it would have many of the BBC dramas, etc. Instead, it is mostly the StarTrek:NG Reruns channel. PBS shows more British programs than BBCA does.
